The memory card makes a very good impression and doing its job perfectly. But strongly I recommend ordering the card with adapter. First of all this is very well made and has a clever sliding mechanism that protects the contacts. But what is really important: the transfer speed (should not be underestimated at 4GB). If you load the memory card on the phone (with the SE Media Manager), so that's painfully slow. A folder with 19 tracks (73.5 MB) has required three and a half minutes for the transfer to the phone. This brings me to about 350 KB / s. And 1 GB would therefore require about 50 minutes (which I have not tried). Using the adapter into the USB port, I came to an average transfer rate of 6 MB / s (lots of small files) yesterday. 1 GB is now charged in approximately two and a half minutes. For comparison I have degrees on an 8 GB USB stick (though no-name) charged the same data on the same connection. And I was just on average 800 KB / s, which has so then took the same time for 20 minutes. So to me is worth the extra cost in any case. Highly recommend this card to the adapter therefore.
